Fantasy Threesome

I am married for 5 years now and since the very beginning, I imagine making a threesome with her. Every situation seems to be the perfect to make it real. If they deliver a pizza I imagine my wife opening the door without closes and making a blowjob to the delivery guy, or if a friend comes home I want to tell him to seduce my wife, start drinking and see her losing control..it’s an obsession now…
